Paul is a 2011 comic science fiction road film directed by Greg Mottola from a screenplay by Simon Pegg and Nick Frost. Starring Pegg and Frost, with the voice and motion capture of Seth Rogen as the titular character, the film follows two science fiction geeks who come across an alien. Together, they help the alien escape from the Secret Service agents who are pursuing him so that he can return to his home world. The film is a parody of other science-fiction films, especially those of Steven Spielberg, as well as of science fiction fandom in general.
